My Kepware OPC-UA server is installed locally, so first I'm just going to put localhost. Here, Ignition can actually discover the OPC-UA server for us, provided we give it an IP address and a port number.

Watch our two-minute video below to see how KEPServerEX solves common connectivity challenges-providing secure and reliable access to real-time industrial data so everyone from the shop floor to the top floor can make smarter decisions. Since I'm going to be connecting to Kepware's OPC-UA server, I'm going to leave OPC-UA selected and click the Next button. The platform is developed and tested to meet our customers’ performance, reliability, and ease-of-use requirements. KEPServerEX leverages OPC (the automation industry’s standard for interoperability) and IT-centric communication protocols (such as SNMP, ODBC, and web services) to provide users with a single source for industrial data.

I am able to connect to the server, but when I try to read an item I get Process finished with exit code -1073741819 (0xC0000005). I started by confirming connection without any security policy, went on with basic 128R. Trying to connect Python to an OPC simulated server using OpenOPC.

The platform design allows users to connect, manage, monitor, and control diverse automation devices and software applications through one intuitive user interface. Hello everyone, I am currently implementing a secure communication (Basic256Sha256) between my opcua client (python code) and server (KEPServerEX 6).

Note: Basic256 is also considered obsolete by the OPC Foundation, the minimum recommended OPC UA Security Policy is then Basic256Sha256. KEPServerEX is the industry’s leading connectivity platform that provides a single source of industrial automation data to all of your applications. There might be an option to still use it with KEPServerEx but I will not recommend using it for something different than testing.
